Ever since the 2.0.0 update made it into Pokémon HOME several players have experienced new error codes. These errors prevent players from being able to access the service or from being able to trade with others. Error Code 2-ALZTA-0005 requires time to fix itself, but Error Code 10015 is more serious and could affect your account from here on out. We'll go over what these error codes mean and explain what you can do to try and fix them.

Why is this happening?

It seems these issues cropped up with the latest Pokémon HOME 2.0.0 update. One of them isn't dire, but the other could have lasting complications.

  • Error Code 10015: Happens when you attempt to transfer a Pokémon. It's not completely clear why this issue is happening, but it could mean Pokémon HOME detects hacked game data like hacked Pokémon or eggs and therefore isn't allowing you to access the service.
  • Error Code 2-ALZTA-0005: Simply means that your game is having issues connecting to the server. This could be due to congestion, a server being down, or other online problems. If this is the issue, you just have to wait until the server is working properly again.

Let's move on to some possible fixes.

If this issue is happening when you attempt to transfer a Pokémon, there are a few things you can try, although you need to be aware that it's not a guarantee that they will fix the issue.

Delete and reinstall Pokémon HOME

Your Pokémon HOME account is tied to your Nintendo ID and therefore will still remember everything you've collected after getting deleted and reinstalled.

Now you should be able to access your Pokémon HOME account again — hopefully, this will have fixed the issue. If it doesn't, then you might need to try something a bit more drastic.

Contact Nintendo Customer Support

Before going for the nuclear option, you should reach out to Nintendo Customer Support and see if they can help you with your issue. You will need to have your Pokémon HOME Support ID, which can be found on the opening menu of the service. We highly suggest you try and see if Nintendo can help you before trying the next option.

Delete and reinstall the Pokémon game

This is a drastic option, but the last one available to you. You can tell where a Pokémon was originally caught by looking at its Pokédex entry in HOME. So for instance, if you can see that a Pokémon that's making the error appear is from Sword and Shield then you can try deleting and reinstalling your Sword or Shield game.

WARNING: Files for Pokémon games are not backed up in the cloud. If you delete your Pokémon game file, it will be gone forever meaning all of the progress and Pokémon still in the game will be lost. Only do these steps if you understand the risks and are ok with going through with them.
